I remember Shravan speaking to Pushkar that every lady has two shades... One that is seen and one that no one can see
So he too feels that his best friend has two shades...
Sumo: Smart confident independent young woman who is cool, funny and free in mind. Rough in approach and speaks her mind out.
Suman: A delicate girl for whom family means everything... Who is soft from inside unlike her Sumo counterpart. And is hesitant too
So, Shravan essentially saw this transformation in front of him, how his Sumo got changed to Suman owing to the situation.
I loved how the writers kept that trait in mind while scripting the scene. Well done!👏
PS: Shravan jerking her and calling her Sumo was maybe to bring back that rough lady. Tears couldn't be shed at such a time... Its time to give back hence the need for Sumo to come out.😃
